Why is audit trail missing from document downloaded through the API?

The audit trail document may be missing when downloading the document based on the Signed event from webhooks. In this case, the downloaded document will contain all signatures but will not have the audit trail attached. This happens because the signing process is not yet fully completed.

To resolve this, wait until the document is fully completed. When this happens, the Completed event will be triggered. You can listen for this event and then call the Download API to retrieve the document with the audit trail attached.

For more details on the Completed event, refer to the API documentation: Sample event data - API Documentation - BoldSign.
